Large prism. Double rotating device arrived back and forth. Smooth helicoid for guide CCD.M48 adapter for the camera. Very sturdy body.
I'm using the OAG with reducer. Can be adjusted out of the prism, so it has gained sufficient viewing. There is no need to look for guide star. The image of exposure 3 minutes to try to 20 sheets composite but never deviated 0.2 pixel. It is 1/20 of when using the guide telescope.
